ELECTRICAL COUPLING.

Specification of Letters Patent.

Patented Mar. 5, 1912.

Application filed October 5, 1910. Serial No. 585,384.

T 0 all'whom it may concern:

lie it known that we, .l i-tssn'li. Hubs and dorm J. Dossenir, oi Syracuse, in. the county of Onondaga and State oi New York, have invented a certain new and useful Electrical Coupling, of which the following is a spoolfication. A

Our invention has for its objbct the production ot a particulartv simple and cflicici t electrical coupling or line tapper, and it consists in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawing in which like characters designate corresponding parts in all the views.

Figure l is an elevation, partly in section, of this electrical coupling or line tapper, the conductors connected by the coupling-being also shown. Fig. 3 is an elevation, similar to Fig. l, of the coupling, the conductors being omitted, and the hinged division of the sleeve member being shown as swung outwardly imposition to permit the insertion of a conductor in the sleeve member. Fig. 3 is a vertical section of this coupling or line tapper, parts being omitted-and Fig. 4 is a detail of one of the clamping elements and contiguous parts.

1 is the threaded stem of the body of this coupling or' line tappcr, the body including a sleeve or band member at one end of the stem for receiving a conductor 3. The stem is formed with a socket -l at its opposite end in which means as a. contractile sleeve 5 is arranged for holding another minductor (3, the contractile sleeve 5 having a tapered conical periphery which fits the complemental circumferential wall at the socket 4.

'7 is a. out or internally thrmided sleeve turning on the lower end of the stem and having an inwardly extending flange S which ehgagcs the outer end oil the sleeve 5 for forcing said. sleeve into the socket. et as the nut is turned onto the stem, and thereby compressing the contractile sleeve 5 on the conductor, (3.

The'portion of the stem adjoining the I sleeve member 9, includes two part-cylin- 11, being hinged at 12 to the other which is usually-integral with the fixed section 10 of the stem. The separable section 9 of the stem is preferably carried by and formed integral with the hinged division 11 of the sleeve or band member. The fixed section of the sleeve member 2 constitutes the greater part of said member, and the end portion 13 thereof to which the division 11 is hinged, overhangs. and is opposed to one end face of the stem the hinge 12 being located at one side of the path of movement of the clamping element. i

14 is the head of the clamping element or' jaw extending into the bore'of the sleeve or band member 2 and having an arcuate face 15 facing the opposed and overhanging portion 18 of the fixed divisionof the sleeve member, and movable toward and from the same. Said element also includes a shank 16 slidable in a slotor passage in the stem or sections 9, 10 thereof, Owing to the overhanging portion 13, which is rigidwith the major part of the sleeve member 2, the head 14 of-tlie clamping element coacts with a. rigid part of the sleeve and thus the conduct-or is clamped between two rigid parts and the movable or hinged portion 11 of the sleeve or band member receives practically none of the clamping strain, and further the conductor is not forced against the joint between the two sections of the sleeve or band member but against a smooth surface.

As here illustrated, one of the sections of the. stem, here shown as the fixed section 10, is formed with a recess 17 in its face opposed to the separable section 9, this recess 17 opening through the periphery of the stem and also into the bore of the sleeve member, and being widened at its ends, and the separable section is also formed with a comple nental recess 18, the two recesses 17 and 18constitnting av transverse slot in which slides the shank 16 of. the clamping element. The head of the clamping element. extends throughout the length of the sleeve or band member and said shank extends the entire length of the head of the clamping element, and is prm ided with enlarged portions 19at its ends which tit the widened portions of the recess 17, said enlarged portions 19 projecting laterally on opposite sides of the stem. The shank 16 is also formed with a slot 20 located in the thinner portion thereof between its enlarged end portions, the slot extending in. a 'direction lengthwise of the stem; and a fastening element, as a screw 21, extends through said slot'aiid into the separable section 9 of the stem for securing the clamping element in position so that it insertion of the conductor 3. The clamp ing element is preferably secured to the separable section 9 of the stem, as owing to the location of the pivot 12, as large an entrance as possible for the cable must be provided for. If such clamping element were carried by the stem, only a limited entrance would be left for the conductor, but when the clamping element is carried by the movable section, the entrance for the cable is enlarged an amount equal to the amount of space occupied by the clamping element when in its normal position. Obviously, if the clamping element were carried by the fixed section 10 of the stem and the pivot 12 is located as set forth, but a small entrance space would be left for the cable irrespective of the distance the movable section 9 were opened.

22 is a nut" turning on the stem 1 and sections 9, 10 thereof against the enlarged projecting portions of theshank 16, the nut servmg to move the head of the clamping member radially of the bore of the sleeve member toward and from the opposing or overhanging portion of the fixed division thereof. During such movement the clamping element is held and guided in its move ment by the enlarged end portions and the contiguous surfaces of the slot formed between the sections ofthe stem.

What we claim is 1. In an electrical coupling, a body ineluding a threaded stem and a transversely extending sleeve or' band member comprising two divisions, one' being fixed to the stem and constituting the greater part of such sleeve member and the outer end portion thereof being opposed to and overhanging one end face of the stem, the other division being hinged to the outer end of the fixed division, a clamping element having a head located in the bore of the sleeve member and movable in a direction axially of the stem toward said end portion of the fixed d ivision of the sleeve member, the hinge connecting the divisions being located at one side of the path of movement of the clamping element, and a nut turning on thestem and coacting with the hinged division and With the clamping element, substantially as and for the purpose specified.

2. In an electrical coupling, a body including a threaded stem and a transversely extending sleeve or band member at one end of the stem, the portion of the stem adjoining the sleeve member comprising two partcylindrical sections coinpleinental to each -other, one section being other, one section being fixed .and the other separable from the fixed section, and the sleeve member including two divisions, one being fixed to the fixed section of the stem and constituting the greater part of the sleeve member and the outer end portion thereof being opposed to and overhanging one end face of the stem, and the other division of the sleeve member being hinged to the outer end of the fixed division, the separable section of the stem being carried by the hinged division of the sleeve member, a clamping elementhaving a head located in the bore of the-sleeve member and movable in a direction axially of the stem toward said opposed end portion of the fixed division of the sleeve member, the hinge connecting the'divisions being located at one side of the path of movement of said element, and 'a nut turning on the stem and the sections thereof and coacting with the clamping element, substantially as and for the purpose set forth. 0 3.
